/* ---------- the sand sequence on a part page ----------
   Three stages, in this order: the Book's title fades in letter by letter,
   the letters blow away downwind, and the numeral resolves in the space they
   leave. build.py bakes each letter's two delays and its own drift into
   inline custom properties, so the stagger is scaled to the length of the
   title and every Book page runs to the same clock however long its title is.

   The title is laid over the whole leaf rather than stacked above the label,
   so the numeral appears exactly where the title was standing rather than
   somewhere underneath it. Words are inline-block: a line may break between
   words and never inside one.

   Note on the two animations per letter. sandOut is declared with `both`, so
   during its delay it holds its own first frame -- and its first frame is the
   fully-arrived letter, which is precisely what sandIn finished on. That is
   what lets the two run back to back on one element without the second one
   wiping out the first while it waits. */
/* Tracking and word space have to be set against each other. These titles
   are capitals, and tracked-out capitals need a word space that grows with
   the tracking -- at .12em of tracking against a .42em gap the two readings
   were close enough that the line ran together and you could not see where
   one word ended. The tracking is now half what it was and the word space
   two and a half times, which puts them an order of magnitude apart. */

   title once from the container instead of spelling it out. That wrapper is
   the ONLY child of the flex box, so flex gap had nothing to apply between --
   and because the builder joins the word spans with no whitespace at all,
   there was no word-space in the markup either. The words were separated by
   precisely the trailing letter-spacing of their last letter, which is to say
   by exactly the same distance as the letters inside them, which is exactly
   what a reader reported: you could not see where one word ended.
